Title: Driving controller for antenna
Inventor: HAMATSU KIYOUSUKE
IPC: H01Q3/02
Filed: 1979-01-11
Abstract: PURPOSE:To improve angular precision as to antenna drive by digitally providing angle detection of an antenna, setting of a command angle and arithmetic of calculating an angular error. CONSTITUTION:The output of a command-angle setting encoder is denoted by thetaR the output of an antenna-angle detecting encode is by thetaA, and error signal 90 expressed digitally is by thetaE, providing thetaE=thetaR-thetaA. Therefore, the output of subtracter 31 is D/A-converted into error signal 91 and after amplification 33, servomotor 4 is driven through motor driver circuit 34. As a result, motor 4 drives antenna 6 with thetaE=0 and angle thetaA of antenna 6 becomes equal to command angle thetaR. Thus, setting a random angle using encoder 25 on the basis of a digital number allows the angle of antenna 6 to follow up this command angle. Consequently, the angular precision can be improved by freely increasing the number of bits of a digital code.

Title: Method and apparatus for bell type charging at blast furnace
Inventor: KITA RIYUUJI
IPC: C21B7/18
Filed: 1978-01-14
Abstract: PURPOSE: To effectively carry out the raw material throwing control of blast furnace inlet part, by utilizing charging locus assumed by a new calculation theoretical formula, at the bell type raw material charging apparatus of blast furnace.  
     CONSTITUTION: Construction of bell type throwing machine is determined by falling locus of charging raw material based on the usual formula I at the bell type raw material throwing apparatus of blast furnace. On this occasion, actual falling locus is shifted from assumed falling locus to the side of furnace center and it is not good for blast furnace operation. Throwing of charging material is controlled by a new theoretical formula II by revising the formula I. By the above formula II, the falling locus assumed by the formula II, is accorded with the actual falling locus, because the distance l between the contact point of the large bell 1 and the bell cup 2 being difficult to assume by the usual formula I and the tip end of the bell 1, is accurately found by considering the velocity of raw material immediately after opening the bell 1 and that of at opening time of the bell 1.
